Ultrasonographic view of fluid bronchogram secondary to endobronchial obstruction: A case report

Fluid bronchograms are seen on CT chest and ultrasonography as linear images corresponding to dilated bronchus, filled with mucus, distal to an endobronchial obstruction. They are characterised by anechoic, tubular structures, suggestive of fluid filled bronchi, over the hypoechogenic pulmonary parenchyma, and can be differentiated from blood vessels by the lack of Doppler signal. Ultrasonographic image of fluid bronchogram is very unique and can help to detect collapse secondary to endobronchial obstruction using point-of-care ultrasonography in emergency.
